Abstract

While left-handers have been overrepresented among 7-meter shooters in handball, previous investigators have not found success from the 7-meter line to be related to handedness. Drawing on previous handedness research in sport, we performed two studies to examine possible negative frequency-dependent advantages to left-handedness during 7-meter throws among elite players. In Study I, we analyzed the records of 974 7-meter shooters from Danish and Norwegian elite divisions (485 males and 489 females) and found that left-handed males were overrepresented compared to the prevalence of left-handers in these two leagues, but left-handed females were not. An analysis of covariance showed no statistically significant associations between throwing arm or sex, and success from the 7-meter line. In Study II, we analyzed the records of 899 7-meter shooters at 41 major championships for both males and females between 2007-2023 (442 males and 457 females). We again found left-handed males to be overrepresented compared to their prevalence at the championships, but left-handed females were not. Also, in alignment with Study I, an analysis of covariance found no associations between throwing arm or sex, and success from 7-meter throws. These findings further underline the complexities associated with lateral biases in sports, where there appear to be benefits for left-handed males in the selection process that are not evident during performance execution.

左撇子是否与在 7 米线上取得更大成功有关?各种手球比赛中的 7 米记录分析。
虽然左撇子在手球 7 米投篮运动员中的比例较高,但之前的研究人员并未发现 7 米线上的成功与撇子有关。借鉴以往对体育运动中手性的研究,我们进行了两项研究,以考察精英运动员在 7 米投掷中左撇子可能具有的与频率相关的负面优势。在研究 I 中,我们分析了来自丹麦和挪威精英组的 974 名 7 米掷远运动员(485 名男性和 489 名女性)的记录,发现与这两个联赛中左撇子运动员的比例相比,左撇子男性运动员的比例偏高,但左撇子女性运动员的比例并不高。协方差分析表明,投掷臂或性别与 7 米线投掷成功率之间没有显著的统计学关联。在研究二中,我们分析了 2007-2023 年间 41 次重大锦标赛中 899 名男女 7 米射手的记录(男性 442 人,女性 457 人)。我们再次发现,与在锦标赛中的比例相比,左撇子男性的比例偏高,但左撇子女性的比例并不高。此外,与研究 I 一致,协方差分析发现投掷臂或性别与 7 米投掷成功率之间没有关联。这些发现进一步凸显了体育运动中横向偏差的复杂性,在选拔过程中,左撇子男性似乎能从中获益,但在成绩执行过程中却并不明显。
